The soil I`m trying to make a grounding system for, has a lot of contamination. Petroleum. And the soil is next to the beach.

Instead of a copper rod, use a zinc rod. Im thinking that these are similar to the types of rods that are used for a house ground. A grounding rod is hammered into the ground, and a wire is brazed onto the top and connected to the house safety ground.
Also, you need to determine if the petroleum is 'moving'. That can be difficult to determine. If it is moving your ground state could change. If it isnt, you could use several rods instead.
I suppose that you could use a copper rod that has been hot-dip-galvanized

Part of the problem is that the ground is a connected to the neutral. If this is done wrong u will end up with ac flowing in parallel with your safety ground and ac flowing in your safety ground. This is very bad and if u get a lightning strike u got problems. The ground and the neutral should only connect together at the transformer, many grounding requirements are to connect at the fuse box. To provide the protection use very large MOV at the fuse box about 12v 1000 amps . All other safety grounding will be connected in common. If it is done right the entire ground system will rise and fall together,and there will be no ac flowing in the safety ground. Good luck

You need to take resistance measurments of the soil, this is generally done using the 3 stake, fall of potential meg ohm meter. After determining the ground resistance you will need to contact an electrical engineer who will design the grounding system suitable for your area.
